Using a refined quantitative polymerase chain reaction assay, we compared surface and bottom water concentrations of Vibrio vulnificus with total Vibrio spp. concentrations, fecal indicator bacteria (Escherichia coli and Enterococcus sp.), and enviro

Fine particle deposition in coarser sediment beds plays an important role in biogeochemical cycling in sediments by 1 supplying organic matter, attached microorganisms, and nutrients and 2 mediating interfacial fluxes through changes in permeability.

In estuaries, frequent resuspension and deposition of sediment complicate bacterial transport model development by transporting particle-attached bacteria and possibly inducing bacterial responses, such as growth, degradation, or changes in attachmen

Bacterioplankton response to eutrophication is a critical part of the transition from phytoplankton blooms to bottom-water hypoxia in estuaries. This topic is of particular concern when endemic bacterial populations, such as Vibrio sp., may pose a he

Monitoring of estuarine condition depends on water quality parameters that have significant and interpretable ecological effects and can be assessed either in situ or via rapid laboratory techniques. Two commonly measured parameters are water column

Calculations of interfacial diffusion coefficients are often based on tracer flux or penetration into permeable media or sediments. Based on previous investigations, a new empirical relationship for tracer-based interfacial diffusion coefficients is

Observations of microbial contamination and particle suspensions represent valuable inputs to water quality models that form the basis of regulatory decisions regarding the use of surface waters. The Neuse River Estuary in eastern North Carolina is e

Predictions of the deposition rate of fine particles are integral to the study of the transport of many constituents, including contaminants and organic matter. Generally, fine-particle deposition rates are assumed to be equivalent to the suspension
